505527' h'YLJEhl HHEEY A. D/c/ffE/m/v may be of metal and of anywell-known preferred structure. The upper end of the container is ttedwith the improved dispensing closure indicated generally at I6.

As best shown in Figs. 3 and 4, the improved dispensing closure I6embodies an end plate or wall I1 forming the end or top wall of thecontainer and preferably constructed of sheet metal which may be tinnedor otherwise treated to prevent rust or corrosion. As shown, the endplate or wall has a depending marginal or skirt flange I8 sized andproportioned to fit closely in telescoping relation within the end -ofthe tubular body I4. Also, the skirt flange I8 may be specially formedso as to provide a firm anti- Sift attachment to the body I4 when theflange is inserted into its final operative position in the end of thecontainer. Also, in some cases, the upper end of the body I4 may beprovided with a reinforcing piece or ring for receiving the skirtiiangel I8. Since the .particular attachment of the end wall I'I to thebody I4 of the container does not form a part of the present invention,it is deemed unnecessary to disclose it herein, kand for this reason thepresent showing of the attachment of thev end plate I'I with its skirtflange I8 to the body I4, may be regardedas being merelydiagrammatical.`

y Although Ythe plate I1 is shown as being of substantially the samesize as the end of the body ;I4, it is not necessarily so. It is formedwith a plurality of dispensing openings I9 which may be arrangedY in anydesired form for dispensing or sifting the container contents, and anydesired number of dispensing openings may beprovided. Also, the endplate or wall Il is provided witha centrally disposed attaching openingthrough which attaching means is extended for attaching the outsidecontainer cap or dispensing controlling structure in operative positionoutside of the en d plate I'I. As shown in Figs. 3 and 4, this attachingopening'v2'il is substantially triangular in shape,V the purpose ofwhich is fully described below. Also, the end wall or plate II isprovided with three lugs or offset portions 2I arranged substantially120 apart and which may be conveniently formed as shown by offsettingthe metal slightly. These lugs cooperate in limiting kthe opening andclosing movements of the cap or sifter closure structure as laterdescribed.

. Integral resilient attaching tongues 22 are formed at the edge portionof the central opening 2i) of the end plate or wall I'I, preferably onesuch tongue being positioned at each of the sides of the triangularopening. These attaching tongues 22 may be deflected or swung inwardlyand slots 23 are formed in the plate at the attached ends of the tonguesso as to provide sufficient amplitude of swinging movement therefor; Thetongues 22 have free swinging end portions with. sharp corners or pointsadapted to be embedded or to bite into adjacent surfaces'of the capstructure for retaining the parts in assembled relation.

In the embodiment particularly shown in Figs. 3 and 4, the outer cap ordispensing closure structure embodies a central stationary part ormember 24 which may be conveniently constructed of any of the well-knownplastic materials, and in the embodiment shown is in the form of acirculardisc provided with dispensing openings 25 anda marginal bearingsurface or flange' 29. Each dispensing opening 25 may be surrounded byan interior reinforcing thickening or ange 4 21. The stationary part 24is formed at its inner side with an integral attaching stem or stubshaft 28 which in this embodiment is substantially triangular incross-section to conform approximately to the shape of the triangularattaching opening 20.

An annular part or annulus 29 comprises the outer or movable part of thecap or dispensing closure structure, being also preferably constructedof plastic and having an outer depending skirt flange 30 adapted toengage closely with the outer surface of the upper end of the body I4.At its inner margin the rotary annulus 29 has a bearing seat 3| in whichthe marginal bearing flange 26 of the stationary center part 24 engagesin supporting relation. This structure provides a support for rotarymovement of the annulus 29 to open and close the dispensing openings. Atits inner surface the annulus 29 is formed with six integral lugs 32spaced for contacting respectively with the lugs 2I on the plate Il forlimiting the movement of the annulus 29 both in its open and closedpositions.

A sealing washer or disc 33 preferably constructed of paperboard,cardboard, berboard, or

similarl material is centrally positioned on the inner surface of theannulus 29, and overlapping the inner surface of the stationary centralpart 24 of the cap. The sealing disc 33 has a circular central aperture34 receiving the stem or stub shaft 28, and its margin is formed withdepressed seats or cut-away parts 35 equally spaced along the margin ofthe sealing disc in which are received integral lugs 36 projecting fromthe inner surfaceof the annulus 29. Two of these lugs 36 are received ineach of the depressed seats 35 of the sealing disc substantially at theopposite extremities thereof so as to operatively connect the sealingdisc tothe annulus 29 for,` rotary movements during opening and closingof the dispensing openings. The sealing disc is also formed withdispensing openings 31 spaced to align respectively with the dispensingopenings I9 of the plate or wall I 'I and with the openings 25 of thestationary or central cap part 24.

When the plate or end wall part I1 and the cap or dispensing controllingstructure have been formed substantially as described above, it is avery simple matter to assemble these parts in their operative positionto form the complete dispensing closure I6 'as shown in Figs. 3 and 4.The stationary central part 24 of the cap is assembled with the marginalbearing ange 25 thereof in engagement with the bearing seat 3I of theouter rotary annulus 29, and the sealing disc 33 is placed in positionon the inner surface of the parts 24 and 29 in engagement with thepositioning lugs 36. The attaching stem or stub shaft 28 is then. forcedinto position through-the central opening 20 of the end plate Il whileat the same time the' resilient attaching tongues 22 engage at theirfree ends or edge portions with the corresponding adjacent fiat surfacesof the triangular attaching stem 28, it being understood that thetongues are normally initially positioned so that their free ends denethe opening 20 somewhat smaller than the stem. This operation Willdeflect the tonguesv inwardly slightly and cause the free ends thereofto engage yieldingly withvthe plastic material of the attaching stem,and when the parts are in fully assembled position the ends of the'attaching tongues will be' embedded or will 1bite to some extent intothe adjacent surfaces of the stem, thus holding the parts firmly inpermanently Assembly. of the Vparts. Vini. their correct.o-pe'r-l ative.position lis. facilitated by means of theftriangular stubshaft orzstem28 in. cooperationwith the triangular..openingll'iin. the end plate I'I,andwhen the parts are thus assembled the dis.- pensing openings IS. of:the plateifl'l and thedispensing openings 25 of the stationary part V2tare respectively incorrectly aligned: positions;- The parts of thesifterr. closure. structure. having thus been completely assembled asdescribed,4 the complete; sifter` unit?.y can be. quickly. and.. easilyinstalled at the upper end of. the container bodyV I4 after thecontainer has beenw lled with powder.

In.themodiedembodimentof the improved sifter closnre shovvnliniligs.5: and 6. of the drawing, the general structure andarrangement aresimilar to those. above described. in.V connection with Figs. 1 to 4inclusive and corresponding parts yare designated by thev samerreference numerals. with theadditionof the index a. TheV end plate orwall part lla is constructed and arranged substantially the same as theplate4V Il Withthe exception that ther central attaching opening d issubstantially circularv instead ci triangular. Also, the integralattaching anges 2v2a-are formed on the arc of a ,circleinstead of beingstraightas in the iirst embodiment, hav'- ing circular edge portions forengagement in embedded relation with the outer. surface of'. the

stubshaftor stem 28a which is. also circular iin.:

cross-section.. v

The cap or lsitter closure structure of. the embodiment of.,Figs. 5 and6 has.l an annulus or rotarygpart-Zila similar to the correspondingpart29 of Figs. 3 and 4,-but the dispensing openings. 25a .are positioned inthis rotarypart rather than in the` central part 24a. rIhe central part2da overlies and` engages .in a circular depressed central seat intheouter surface of` the rotary part'29`a and"l hasa circular attachingvstern. `or stubshaft 28a extending through a central opening-'inthepart' 29a and through the central opening lla of the end plate 11a. 'Thesealing disc 332i" may" be constructed of the same material`ra's'described for the sealing disc 33 and isl provided'with a centralopening for receiving theatt'aching stem 28a and provided withdispensing openings 37a aligning respectively with the-dispensingopenings 25a.

The sealing disc 33a is shown as being circular having amarginal notch'or seat 38'i0r receivi'ngf'a positioning 'lu'g '39 projecting from theinnersurface of the rotary member 29a and integral therewith. Also, theouter edge of the circular'sealing disc 33a is received 'closely withintheintegral positioning and stop lugs 4G whichV areA integral With'theinner surface'of the rotary cap 29a. supported andA positioned forrotation with the cap member 29a.

'7, 8 and 9, corresponding' parts are designated by the samereference nun'iertil4 With the addition ofthe index b. In thiselil'bodiment the cap structure or' cap 4I' is pref f ably made of plasticmaterial'-ancv is'n'iad'ev single. integral plastic piece, asdistinguished`- from the two-part plastic cap structure disclosed inFigs. 1 to 6 inclusive. The cap 4l is' also preferably provided with anintegral depending" skirt flange 301) and is formed withsifterorf'd-i'spensing openings 25h.

As in the embodiments previouslydescribed?, the end closure plate orlf'lb shoi'vfniin' 'Fig 7 has a depending skirt ange I8'b` tele--scoping with the upper end of the bo'dy parti |46 of the container. Thisskirt flange may be attached with the wall of the body portion'- in anydesired manner as suggested above"Y in coi'-' nection with. theembodiment ofFig's. 1 to 4 inclusive. Also, .the end wall portion' I'lbvis formed with sifter or dispensing openin'g's'f` I9?) adapted to alignrespectively .with the` openings' 25h in the cap. The end wall or' plateI'Ibi isi further provided with a centrally disposed at# taching opening20h, which asparticularlyshown in Fig. 9 has oppositely disposed sectorshaped' extensions 42 for receiving parts of the plastic cap 4l as laterdescribed.

At its inner side the cap 4I is provided withan; integral attachingstemory stub shaftb which;y as shown, is preferably circular incross-sectionl engaging closely in the attaching openin'g'Zb of' h theplate ilb. At its base portion the attachingstem28b is' formed Withoppositely disposed" eri-'- largements formingstop lugs 43integralwith"`the"v cap 4I and positioned for reception' in tl'lejslots-'s i2 formed in the end plate Hb; The cap struc ture 4| is heldsecurely in assembled rela-tion on'. the top of the container by meansof-'a steel vat-f taching washer 44 having one or more integraliswingable attaching tongues 22h deflected down-f wardly or inwardly atthe underside of the Vatltachingwasher, and having end edgepo'rtionsiprovidedwith sharpc'orners-o'r.A points adaptedn di? be embedded insecuring relatin into the'sur@ face-of the attaching stem 23h.- Theattaching:Y

washer 44 may be dished orconvexed downwardly or inwardly as shown inFig. 7 engaging at its: outer rim with the inner surface of the endplate?. Hb soas to slide over the latter when thefcap is: rotated toopen and close the'dispensi-ng openings-L? As in the case of theattaching tongues described? inthevother embodiments, it will 'beunderst'oodthis mannery the' attaching tongues 'are yieldingly 1urgeddue to the resiliency of the washer material into engaging positionagainst the attaching stem and the free ends are caused to be embeddedor to bite into the surface of the stem, thus holding the parts securelytogether in assembled relation.

, Interposedbetween the end plate lib and the plastic cap 4l within anappropriate recess formed in the innerr surface of the cap is a sealingdisc or Washer 33h preferably of sor'ne appropriate sealing material,such for example, as paperboard, berboard, or the like. The sealing discis also provided with dispensing openings 31h spaced for alignmentrespectively with the openings in the cap and end plate, and has acentral opening 34o for closely receiving and conforming to the inner orbase portion of the attachingpstem 28h together with the oppositeextensions or enlargements 43 thereof, thus nonrotatably attaching thesealing disc to the undersurface of the cap 4I.

g It will be understood from the foregoing description that theembodimentJ of the improved sifter closure of Figs. 7, 8 and 9 will havethe advantages above described in connection with the other embodimentsboth during assembly and in Operation. In order to open or close thedispensing openings, the closure cap 4l may be rotated by engagementthereof by the user, and as in the other embodiments, the cap may beconveniently grasped at the outer edge or depending skirt flange which,if desired, may be serrated or roughened to form a good friction grip.It will be seen that the sealing disc 33h is rotated with the cap 4I andwhen the dispensing openings in the end plate and cap have been movedinto aligning position as shown in Fig. '7, the integral stop lugs 43 ofthe cap willl engage in limiting relation with the adjacent edges of thesector openings or slots 42 in the plate Hb. Similarly, when the cap-isrotated in the opposite direction to close the dispensing openings,these stop lugs will engage in limiting relation with the opposite edgesof the openings 42.

In the further modified embodiment of Figs. 10, 11 and 12, a one-pieceplastic cap structure is used as in the embodiment of Figs. '7, 8 and-9, and other structural features are also similar and correspondingparts are designated by the same reference numerals with the addition ofthe index c. In this embodiment, however, the top or end wall structurellc of the container body |4c is made of paper or fibrous stock the sameas the body |40 and may be attached to the body in any desiredwell-known manner. Since the attachment of the end l'lc to the body |40may be of any desired known structure and does not form a part of thepresent invention, it is deemed unnecessary to disclose it in detail.

, As in the embodiment of Figs. 7, 8 and 9, the plastic cap structuresic is provided with an inner integral attaching stem or stub shaft 22opreferably substantially circular in cross-section as shown, andprovided with one or more eX- terior longitudinal ribs 45, three beingshown spaced substantially 120 apart. These ribs as shown may extendsubstantially for the full length of the attaching stem 22e. Thisattaching stem 22C, as best shown in Fig. l2, is received within thecentral attaching opening 26e in the end wall llc, said opening beingprovided with cut-away marginal slots or seats 45 adapted respectivelyto receive the ribs or stop lugs 45 to limitrotative movements of thecap Mc. The slots or seats are each of sufficient length to permitsufficient amplitude of rotation of the cap to position the same fordispensing the container contents when the dispensing openings 25o and|9c in the cap and Wall structure are respectively in alignment as shownin Fig. 10, and when these dispensing openings have been disaligned whenthe cap is closed.

As in the embodiment of Figs. '7, 8 and 9 above described, an innerseparate attaching washer 44e is employed as shown in Figs. 10 and llhaving integral attaching tongues 22o deflectable inwardly andengageable at their free ends in securing relation with the attachingstem as described above in connection with the other embodiments. Inthis case, however, there are a series of attaching tongues 22oextending substantially around the inner opening Vof the attachingwasher 44o and formed by cutting small radial slots 41 in the washer.Also, the washer 44C is formed at the margin of its central receivingopening with three seats or lpockets 48 spaced for receivingrespectively the ribs 45 of the attaching stem whereby the washer isconstrained to rotate with the stem and the cap 4Ic. Also, in thisembodiment the attaching Washer 44e preferably has a fiat inner marginalsurface engaging in close sealing relation with the inner surface of theend wall or head Ic so as to improve the anti-sift qualities of thedispensing closure. The washer is also formed with dispensing openings49 respectively aligning with the dispensing openings 25e of the capalc.

From the foregoing description it will be understood that the dispensingcap 4 lc may be rotated by grasping the skirt flange 30e so as to bringthe dispensing openings in the cap and washer 44e into alignmentrespectively with the dispensing openings in the head lc as shownin'Fig. l0, in which position the rotative movement of the cap will bestopped by engagement of the ribs or lugs 45 with the respectiveadjacent ends of the slots 46 of the end Wall llc. Similarly, when thecap 4Ic is rotated in the opposite direction to close the dispensingopenings, the movement will be stopped by engagement of the ribs 45 withthe opposite terminals of the slots 46.

Since certain changes may be made in the above construction anddifferent embodiments of the invention could be made Without departingfrom the scope thereof, it isintended that all matter contained in theabove description or shown in the accompanying drawing shall beinterpreted as illustrative and not in a limiting sense.
